I'll take a stab here since this is my area...
FCX is uninvestable right now IMO (even though I own a tiny bit in my commodities account...haha). Grasberg, their behemoth mine in Indonesia is a disaster. They are trying to work out an agreement with the Indo government on how to get some money out of the deal (the government is basically seizing the asset), but until something happens with that, I don't like FCX. When it is resolved, the stock could go up/down big in a single day, but there is no way to know it will turn out. My guess is the drop in earnings in 2019 is a result of analysts taking Grasberg out of their valuation (it's the biggest driver of earnings for FCX).
As R59 mentioned, I like CMMC.to the best of the copper producers. They are low cost, generating good free cash flow and using the cash to pay down debt. They also just acquired an asset (the jury is still out on whether that's good or bad). I'm up about 200% on my CMMC. I tried trimming it the day I froze it the PSL contest, but I couldn't sell my shares at the close. It's down 25% since then :(
Other miners that I really like are TV.to (zinc mining play) and PAAS (silver tax loss candidate that Nelson also recently talked about). Finally, I love uranium (CCJ is the big one here). Uranium prices are going up in my opinion...a lot.
Just trying to make a few bucks.
